Ok i can help 4/5 * 15 is 12/1 or 12
Answer:
56
Step-by-step explanation:
Given data:
{1 ,2 ,4, 6, 8, 9}
Formula for combinations is used since the order does not matter and repetition is allowed.
nCr = (n + r -1) /(r! * (n-1)!) where n is the total number of items and r is the items to be picked
6C3 = (6 + 3 - 1)! /(3! * (6 -1)!
6C3 = 8!/(3! *5!) Simplifying the factorials)
6C3 = 40320/(6*120)
6C3 = 40320/720
6C3 = 56
The question gives us that cot ∅ = 1.5, and we need to find tan ∅ (∅ being theta). So, cotangent, which is <em>cot</em>, is equal to adjacent over opposite, and tangent, abbreviated <em>tan</em>, is equal to opposite over adjacent. Basically, we need to take the inverse of the given value for <em>cot</em><em>. </em>Doing so gives us 1/1.5, which is approximately 0.667. Therefore, the answer to your query is A. Hope this helps and have a great day!
Answer:
99 F
Step-by-step explanation:
"Three lower" means it was the original temperature - 3, so if the original temperature was 102, we have the equation:
102 - 3
99 F
so 99 F is the answer
